This invention relates to household plumbing fixtures and 'hasparticularly reference to swin spout mixing faucets, theinveiifiioh'being directed to certain improvements "in the "manner ofassemfbiing the spout with and mounting the same to swing relative tothe faucet body and to the means for effectively sealing the spoutagainst leakage a't'it'he region of its connection with the 'faucet'body"The invention broadly comprehnds a simple and effective .means ofconnection between the faucet body and spoutwhich when assembled permits0f afllim i ted swinging movement of 'thespout with reference thereto,while preventing disas- .sembly thereof without first remd ing thebohiie't's of the valved inlets of the 'faucetbody 'tothereby minhn'izethe likelihood of surreptitious 'r'emoval of the spout elements from thefixtures. ,Animpontan't feature of the invention consists in theemployment .o'f a simple threaded connection between the spout andfaucet :body 'whi'ch greatly facilitates the'labor of 'asseinblywhilepermitting oi the use o'fl'an elastic fgasketwhich "is soassociated with'the spout and 'faiic'et body :as to efiectually seal thesame against leakage at their juncture, thereby avoiding the necessityof resorting to expensive s'tiifiing boxes and packing glands and thelikwith the attendant requirement to frequently renew the packingandstoffin As a :further feature, the invention comprethends ai swingspout mixing {faucet structure "in which the tauoet body and swingingspout at "the regions of their threaded connection may have portions orinserts fashioned of a Idifferentma- & terial or ial'loyvfrom that ofthe remainder of the spout and body to provide for a non-corrosive,wearresisting connection. 7 7

With the previously enumerated and other objects in view,'theziollowingspecification setsforth r the "inventionf-inigreater detail, while theclaims mark out and define the scope of the invention, thestructurebeingillustrated in the accompanying drawing, in which: i

Fig. 1 is a fragmentary front view of a swing spout mixing faucetconstructed in accordance with the invention, showing the spout swung tothe limit of its movement in engagement with the bonnet of the righthand valved inlet end of the faucet body, the medial outlet portion ofthe body and intake end of the spout being broken away and shown insection to disclose the sealing gasket.

Fig. 2 is a similar view showing the spout swun to the limit of itsmovement in engagement with the bonnet or the left hand val ved in-letor the faucet body. V V

Fig. 3 is {a perspective view or the insert nortion'at theinlet end ofthe spout.

Reierrmg to the drawing by characters of reierence, A esignatesgenerally the body-of a swing spout mixing 'fancc't which is ofelongated tiibular formation and rovided with a longitudinal passage I'D'defining' a mixing chamber, the opposite ends of which communicate withthe valved inlet ends defined by enlarged portions H and I2 attheopp'osite ends of the "faiicetbody and constitiiti'ng' valve casingsover "whichvare threadedly engaged "the usual banners I3. The medialportion I4 of the body A is enlarged to provide a boss which is formedwith an inner threaded outlet bore l5-"tlre innermost end of which'opensinto the mixing chamber or passage f0 and the outer end of whichcommunicates with the innermost end of an enlarged outer bore Hi openingat its outer end through "the outer surface of the boss or emergedmedial portion of the body. This defines fa shoulder ll at the junctureof the inner and outer 'bore's -l-5 and T6 which shoulder is disposedwithi-nt'he confines of the boss or enlarged medial ortion M adapted toserve a purpose wljichis hereinafter explained.

The spout, designated generall by the referencefchaira'cter *8, includesan elongated tubular shank portion 2 0 havin'g-a downturned outer freeoutlet end no n2! andanang'ulated inner intake end "having a reduceddepending trunnion ortion 23 of a diameter to snueiy -'fit within theouter 'b'or'e 16 "of the faucet "body aA re'd'uce'd a1 portion protrudesfrom the trunnion n =23 and is formed with a still 'r-urther red uced 'kter i'ofly flrraded "eXtlelthity 2'5 en ageable "Within-thethreadedinne'r bore 1'5 to efiec't rotatory connection between the spout B andfaucet body A and to establish communication between the :a'nd mix ngchamber or pas- {saQed-t, ashooideme being defined at the Junctu i e ofthe reduced terminal -21 with the t1-u'na ien "2 3.

An elastic gasket 21 of rubber or an equivalent material is provided,the internal periphery of which is of a size to snugly fit around theterminal 24 and said gasket is interposed between the faucet bodyshoulder l1 and the spout shoulder 26 to lie within the outer bore l6 ofthe faucet body when the spout is assembled therewith. This assembly isaccomplished before the bonnets are applied to the end portions II andI2, it being apparent that the reduced threaded extremity is engagedwith the threaded inner bore l5 and the spout rotated a multiple numberof turns until the end face of said extremity is substantially fiushwith the inner end of the inner bore I5, as shown in Fig. 2. It isevident that the outer free outlet end portion of the spout B clears theupper faces of the end portions l l and I2 during the assembly but uponemplacement of the bonnets l3, the same act as stops disposed in thepath of movement of the outer end 2! of the spout B, thus serving tolimit the same to swing: ing movement therebetween. The gasket 21,

which is of such a length that it will be main-- tained undercompression at all times after the spout B is assembled with the faucetbody A and subsequent to the application of the bonnets I3, will havesufficient longitudinal expansive action to effect a seal at all timesthereby compensating for the slight relative movementof the shoulders I1and 2 6 toward and away from each other due to the threaded swingingconnection between the spout and body. As illustrated, the normal outerdiameter of the gasket 2'! is slightly less than the inner diameter ofthe outer bore [6 to afford a clearance space for the radial outwardexpansion of the gasket as it is compressed longitudinall between theshoulders I! and 26 during their movement toward each other when thespout B is swung from the right hand position shown in Fig, 1 to theleft hand position shown in Fig. 2.

What is claimed is:

1. In a swing spout mixing faucet, a faucet body defining a mixingchamber and having inlet valves at the opposite ends thereof includingremovably associated valve bonnets, said faucet body having an outletintermediate the ends thereof, a spout having an intake terminalthreadedly engaging said faucet body outlet and communicating with themixing chamber and plied to the inlet valves serving as stops to preventcomplete rotation of the spout and to limit the same to swingingmovement therebetween.

2. In a swing spout faucet as set forth in claim 7 1, in which the spoutintake terminal and faucet body outlet are respectively formed withspaced complementary shoulders located within the confines of theoutlet, and an elastic sealing gasket interposed between said shouldersso as to be under compression and impinged thereagainst in any relativeposition of the spout with reference to the faucet body between thelimiting stops defined by the inlet valve bonnets.

3. In a swing spout mixing faucet, a body defining a mixing chamberhaving valved inlets at the opposite ends thereof and a recessed outletintermediate said ends, removable bonnets carried by the valved inletends of said body, a spout having an outlet end and an angulated intaketerminal threadedly engaging within the recessed outlet of the body andcommunicating with the mixing chamber, the valved inlet ends of the bodybeing so located as to clear the outlet end of the spout to permit ofcomplete and multiple rotation thereof for engaging the intake endthereof with and disengaging the same from the faucet bod duringassembly and disassembl of the spout and body, said valve bonnets beingso located on the valved inlet ends of the body as to intersect the pathof movement of the outlet end of the spout to serve as stops to limitthe spout to swinging movement therebetween when the bonnets areapplied.

4. In a swing spout mixing faucet as set forth in claim 3, wherein therecessed outlet of the faucet body is formed with an inner reducedthreaded bore and an outer relatively larger bore defininga shoulder andwherein the intake terminal of the spout is formed with a reducedthreaded extremity engaging the inner bore and with a larger trunnionportion fitted within the outer bore and defining at the juncture withthe extremity a shoulder complementary to the outlet shoulder, and anelastic sealing gasket located between said shoulders and maintainedunder compression in any relative position of the spout with referenceto the faucet body between the limiting stops defined by the bonnets,

5. A swing spout mixing faucet including an elongated hollow bodydefining a mixing chamber, an outlet boss intermediate the ends thereofhaving a threaded inner bore opening into the mixing chamber and havinga relatively larger outer bore communicating with the inner bore andopening through the outer surface of the boss with a shoulder defined atth juncture of said bores, a spout having an angulated end portionrespectively forming a trunnion fitted within the outer'bore and areduced threaded terminal engaging the threaded inner bore with ashoulder defined at the juncture of said trunnion and terminal, theshoulders of said spout and bore being spaced apart, an inlet valvecasing at the opposite ends of the faucet body so arranged as to permitof multiple rotation of the spout for threadedly assembling the samewiththe faucet body, valve bonnets removably associated with the inlet valvecasings and normally disposed in the path of movement of the free end ofthe spout for preventin disassembly of the spout and serving as stops tolimit the spout to swinging movement therebetween, and an elasticsealing gasket located between the shoulders so as to be compressedtherebetween and maintained under compression in any position of thespout with reference to the faucet body between the limiting stopsdefined by the valve bonnets to seal the intake end of the spout at itsjunc ture with the faucet body.
